Despite the title, this is not a cache for Canis Minor although I certainly hope he comes out to find it.
The area in which the cache is hidden used to be an awkward triangular plot of land where some curvy streets intertwined. The villlage of Downers Grove reworked the streets a number of years ago which created this little oasis that is now landscaped with prairie plants.
It is located on Clyde Avenue within a residential neighborhood so please use stealth and respect.
